38 * @class ImageFeatureManager
39 * @brief This class provides methods to generate individual feature data from an individual image data and collect to feature set file.
43 * The %ImageFeatureManager class provides methods to generate individual feature data from an individual image data. This class also provides methods to manage image feature set which is a collection of individual feature data.
45 * The following example demonstrates how to use the %ImageFeatureManager class.
48 * void GenerateImageFeatureSet()
50 * Tizen::Uix::Vision::ImageFeatureManager imageFeatureManager;
51 * imageFeatureManager.Construct();
52 * imageFeatureManager.AddFeature("/opt/usr/media/Images/image1.jpg");
53 * imageFeatureManager.AddFeature("/opt/usr/media/Images/image2.jpg");
54 * imageFeatureManager.AddFeature("/opt/usr/media/Images/image3.jpg");
55 * imageFeatureManager.Flush("/opt/usr/media/Images/testFeatureSet.xdb");
58 * void AddImageFeatureSet()
60 * Tizen::Uix::Vision::ImageFeatureManager imageFeatureManager;
61 * imageFeatureManager.Construct();
62 * imageFeatureManager.Load("/opt/usr/media/Images/testFeatureSet.xdb");
63 * imageFeatureManager.AddFeature("/opt/usr/media/Images/image1.jpg");
64 * imageFeatureManager.AddFeature("/opt/usr/media/Images/image2.jpg");
65 * imageFeatureManager.AddFeature("/opt/usr/media/Images/image3.jpg");
66 * imageFeatureManager.Flush();
70 class _OSP_EXPORT_ ImageFeatureManager
71 : public Tizen::Base::Object
76 * This is the default constructor for this class. @n
77 * The object is not fully constructed after this constructor is called. @n
78 * For full construction, the Construct() method must be called right after calling this constructor.
82 ImageFeatureManager(void);
85 * This is the destructor for this class. @n
86 * The resources are deallocated by this method.
87 * This destructor overrides Tizen::Base::Object::~Object().
91 ~ImageFeatureManager(void);
94 * Initializes this instance of %ImageFeatureManager and create image feature set. @n
95 * Every application must call %Construct() before calling any other methods of %ImageFeatureManager.
99 * @feature %http://tizen.org/feature/vision.image_recognition
101 * @return An error code
103 * @exception E_SUCCESS The method is successful.
104 * @exception E_UNSUPPORTED_OPERATION The Emulator or target device does not support the required feature.
105 * For more information, see <a href="../org.tizen.gettingstarted/html/tizen_overview/application_filtering.htm">Application Filtering</a>.
106 * @remarks Before calling this method, check whether the feature is supported by %Tizen::System::SystemInfo::GetValue() methods.

120 * @exception E_INVALID_ARG The specified feature set file path is invalid.
121 * @exception E_OUT_OF_MEMORY The memory is insufficient.
124 * - If a feature set file exists, it is updated.
125 * - If a feature set file does not exist, it is newly created.
126 * - It is not mandatory to call this method to create new feature set file, but Flush() must be called with valid feature set file path.

144 * @return A feature index of newly and successfully created feature, otherwise returns -1.
146 * @param[in] imagePath The input image file path
148 * @exception E_INVALID_ARG The specified input parameter is invalid.
151 * - The specific error code can be accessed using the GetLastResult() method.
152 * - Input image file must be one of the supported image file formats.
153 * - Calling this method actually means 'Mark As Add Feature'.
154 * And the marked feature data will be added to a feature set file after calling Flush().

240 * - If @c featureSetFilePath is not decided or is same as the file path used in Load(), the loaded feature set file is updated.
241 * - If @c featureSetFilePath is not same as the file path used in %Load(), the loaded feature set file remains as is and new feature set file is created.
242 * - If @c featureSetFilePath is @c null, the feature set file loaded by %Load() is overwritten.
243 * - If @c featureSetFilePath is not decided or is same to file path used in %Load() and the loaded feature set file is read-only @c E_INVALID_ARG exception will be returned.
244 * - If %Load() is not called to create new feature set file, this method must be called with valid @c featureSetFilePath.
